whatever your mapping for keys on the stick is, ‘select+start’ is the default hard-quit back to emulation station.

The RPI2 can power (some) external drives just fine. You can add max_usb_current=1 to the config and it bumps port voltage up. I used a hub (pictured in the center) because I also have bluetooth and wifi dongles running on it. They draw a fair amount of power on their own.

If I just had the drive hooked up, the PI can power it with no problem.

I think it can be done, if you hand-shorten all your cables, or bypass ‘plug and play’ and wire them directly to the pi. Most of the space I used came from using actual cables with connectors and snaking them around the case.

What are your transfer speeds like? I tried with Filezilla I still cap around 250 kb/s

You’re awesome, thanks. That confirms it’s connected and at the right size ;)

I think it may be working now:
*deleted altered entries in /etc/fstab
*formatted 500gb drive to ext4
*ftp’d an iso over to it as a test (took a horrible long time at around 250k/s)
*altered path for PSX to /media/usb0/psx , ISO is found and working

Is there a way to tell by command what capacity there is available on the drive? or through emulationstation? I can see the SD card capacity through ‘sudo blkid’ but that doesn’t list the external drive space.

I bet that’s what my problem is, I’ve been tweaking with fstab file thinking it matters here

[disrespect]

Insecure spike did you have to edit fstab to make the drive mount automatically at every boot? I don’t see anything about it there.

if no good I’ll go through my step by step set up

Let me see what you did, maybe it will show where I went wrong. For what it’s worth, I see my drive on sudo blkid but not ls /media/usb* (which SHOULD show a drive, right?)

2.5 is more than enough to power the PI at overclock. If you add in peripherals, it’s still enough to power most external (usb powered) hard drives, with a port adjustment in the config.

If you are just worried about controllers and things, you have more than enough power there. My setup is 2amp, and it powers PI at overclock, two controllers, a keyboard, a usb wifi stick, and an external hard disk.

I’m currently using the original power switch from the PS1 shell I built into a PI2. I have it interrupting +5 to kill power to the board and a secondary power LED.

If I send term signal through retropie, and shutdown everything so that it’s in an ‘off’ state but still powered, how is this any worse than a mausberry killing the power? (Honest question) I have been using it like this for about a week now.

Is it powered by the Pi or it’s own power source/usb hub? I read alot of people having issues with external drives being underpowered, causing them to not come up.
